Estimation of stature from sternal lengths. A correlation meta-analysis

Area of Science:

• Forensic Anthropology
• Human Osteology
• Biometrics

Background:

• Estimating living stature is crucial in forensic anthropology.
• Long bone lengths are traditionally used, but alternatives are needed when bones are damaged or missing.
• The sternum and its components offer a potential alternative for stature estimation.

Purpose of the Study:

• To conduct a meta-analysis quantifying the correlation between sternal length and stature.
• To evaluate the reliability of sternal measurements for stature estimation in forensic contexts.

Main Methods:

• A meta-analysis was performed, synthesizing data from nine studies.
• Included data from 1118 sternal bones.
• Correlations between various sternal lengths (meso-sternum, total sternal length, manubrium, body) and stature were analyzed.

Main Results:

• The meso-sternum (manubrium + body) showed the highest correlation with stature (53.5% in males, 55.42% in females).
• Total sternal length was the second most correlated metric.
• Autopsy subgroup analysis indicated a higher correlation for meso-sternal length (58.2%).
• Females generally exhibited better correlations than males for most sternal measurements.

Conclusions:

• Meso-sternal length is the most correlated sternal metric with stature.
• Sternal length measurements should be used cautiously for stature estimation, especially when long bones are available.
• Further research with larger, diverse populations and consideration of sternal fusion status is recommended to improve reliability.
